Description:
BME280 is a precision sensor, not only the pressure and the temperature, this sensor can measure humidity. The board has selectable I2C address jumper (solder link GS2), I2C pull-up resistors, 7 pin header 2.54mm, and two mounting holes 3.5mm.
Specifications:
VDD main supply voltage range: 1.71 V to 3.6 V
VDDIO interface voltage range: 1.2 V to 3.6 V
Digital interface: I2C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz)
Current consumption 1.8 uA @ 1 Hz humidity and temperature
2.8 uA @ 1 Hz pressure and temperature
3.6 uA @ 1 Hz humidity, pressure and temperature
0.1 uA in sleep mode
Operating range -40 to 85 C, Humidity: 0-100%, Pressure: 300-1100.
Humidity sensor and pressure sensor can be independently enabled/disabled
Default setting of the board
single power rail Vdd=Vdd_IO (solder link GS1)
pull-ups resistors (R2, R3) 10k
protocol selector resistor 0ohm (R1)
decoupling capacitors 0.1uF on both power supply pins Vdd & Vdd_IO
If you connect board to both power rails VDD_IO 1.8V and VDD 3.3V be sure to remove the power rail jumper GS1.
